2. Description of the Related Art Conventionally, a developed negative film (or positive film) is used as an image signal by an image system and an electric circuit used in a video camera or the like and is connected to an image device such as a television. A film viewing device for projecting images is known.

In this apparatus, when viewing a vertically photographed frame, the image pickup portion or the film portion is rotated by ± 90 ° with respect to the normal position.

On the other hand, there has been proposed a camera using a film having a magnetic recording unit, which is known in US Pat. No. 4,864,332, US Pat. No. 4,977,419, etc., and a photo video using the film photographed by this camera is proposed. Is also proposed.

In the magnetic storage unit, various kinds of information related to photographing, such as the photographing date, character caption, shutter speed and aperture value at photographing, lens focal length used,
There is a shooting posture (normal position or vertical position). It is also possible to specify a print format in which the screen aspect size at the time of printing can be arbitrarily selected.

According to the film viewing apparatus using the above information, for example, a frame photographed in the panorama size is displayed on the television screen with a panorama size screen aspect ratio (about 2.8). A series of processing such as reading and video signal processing is performed.

Further, if the frame is photographed in the vertical position, it is possible to rotate the image pickup system of the film viewing apparatus by means of a motor or the like based on the read information and display it on the television screen as an upright position. .

[0008]

However, in the above-mentioned conventional example, the film viewing apparatus side faithfully reproduces information on the basis of the print format and the vertical and horizontal position information specified by the photographer at the time of shooting, which has the following drawbacks. It was

[0009] When a frame shot in a vertical position and having a particularly high screen aspect ratio is played back, there is too much blank space on the cathode ray tube surface of the television, resulting in an unsightly playback screen.

Consider, for example, a case where a so-called panoramic size having a screen aspect ratio of about 2.8 is designated as a print format and an image is taken in a vertical position. When a film viewing device for reproducing the above-mentioned information while reading the magnetic recording portion of the film recorded on the magnetic recording portion is connected to a so-called high-definition type television or monitor with a screen aspect ratio of about 1.8, the television screen The ratio of the reproduction screen to the area ratio becomes a small value of about 0.2, and most of the image has an impression like a margin. The present invention has been made in consideration of the above circumstances, and it is an object of the present invention to make viewing on a television screen easier to see when playing a vertically photographed frame, particularly a frame having a high screen aspect ratio. .

[0011]

According to the present invention, in a film viewing apparatus using a film having a magnetic recording portion, information reading means for reading information recorded on the film and a vertical position frame are reproduced. And image control means for changing and outputting to another print format having a small screen aspect ratio for the print format at the time of shooting, and the information reading means is magnetic information or optical information of a film having the magnetic recording section. The target information or both are read.
